Privacy Policy

1. Overview

Calcultron ("we", "us", "our") operates the calcultron.com website. This page informs you of our policies regarding the collection, use, and disclosure of information when you use our service.

2. Information We Collect

Calcultron is designed with privacy in mind. Our calculators run entirely in your browser — no calculation data is transmitted to our servers.

• Local Storage: We store your cookie consent preference and theme settings locally in your browser using localStorage. This data never leaves your device.
• Analytics: We may use privacy-respecting analytics (such as Umami) to understand general usage patterns. This data is anonymized and does not include personal information.
• No Account Required: We do not require registration or collect personal information such as names, email addresses, or phone numbers.

3. Cookies and Local Storage

Calcultron uses minimal browser storage:

• Cookie Consent Preference: Stored in localStorage to remember your consent choice.
• Theme Settings: Stored in localStorage to remember your display preferences.

We do not use tracking cookies or third-party advertising cookies.

4. Third-Party Services

Our website may load resources from third-party services:

• Google Fonts: We use Google Fonts for typography. Google's privacy policy applies to their font delivery service.
• Tailwind CSS CDN: We load the Tailwind CSS framework from a CDN for styling.

5. Data Security

All calculations are performed client-side in your browser. No financial data, health data, or personal calculations are ever stored on or transmitted to our servers.

6. Children's Privacy

Our service is available to users of all ages. We do not knowingly collect personal information from anyone.

7. Changes to This Policy

We may update this privacy policy from time to time. We will notify you of any changes by posting the new policy on this page and updating the "last updated" date.
